To all whom it may concern:

Be itknown that l, JAN SoNNEvnno, subject of the Queen of the Netherlands, residing at Schela Gura Ucnitsei, near Targoviste, Roumania, have invented certain new and useful Improvements in Apparatus for Extracting Liquids or Gases, of which the following is a specification.

This invention relates to a new apparatus for drawing ofl liquids or gases or both liquids and gases, under pressure, and containing mineral substances in granular condition from a container or the like and it relates in particular to apparatus for the extraction of petroleum or otherhydrocarbons containing sand or the like from a well,

The known manner of securing under such circumstances a regular ejection of the fluids is by means of valves, with which the assage of the fluid may be throttled. uch va ves however, when throttling the passage of fluid, prevent same from passing'in a straight line through the valve, part of the valve member proper then projecting into the path of the fluid Consequently such valves in a short time are fully ground out by the solid substances contained in the fluid and in case the ejection takes place under high pressure the valves are even totally destroyed in a'few hours.

-Accordin to the resent invention the discharge 0 the fluid liquids or gases under pressure and containing mineral substances in granular condition) from the well, which is closed for the rest, is conducted through one or more annular or pierced members which are connected either directly or-indirectly to the well, said member or members providing a passage for the fluids smaller than the bore of the rest of the conduit, the inner walls of said member or members being substantially. parallel to the path of the solid parts contained in the fluid to be discharged.

The said annular or pierced member or members are preferably of cylindrical shape with a central bore. They may consist of a metal, an alloy or a mineral of the same or greater hardness than iron, or they may consist of either of these materials in granular condition and bound by a binding agent.

They are either directly or indirectly connected to the well, or'to the pipe by which liqulds and gases'are discharged from the well, or they are mounted on the mouth of said discharge pipe, but always in such .a

way as to force the fluids to be discharged to pass through it previous to entering a space of lower pressure.

Referring to the drawings, Figure 1 shows one embodiment of my invention; Fig. 2 IS a cross section through a form of nozzle preferably employed by me; and Fig. 3 is a cross seption through such a nozzle.

In F g. 1 of the drawing, 1 designates a cylindrical nozzle having a bore of a diameter which is reduced with regard to the bore of the discharge pipe 2, on the mouth ofwhich it is mounted, the discharge pipe 2 being connected to the well 3.

Fig. 2 shows the discharge member or nozzle 1 on a larger scale. The inner wall of the nozzle is curved near its one end, so as to practically prevent it from being hit by the solid substances contained in the liquids or gases, thereby protecting it against being ground out in a very short time.

Fig. 3 is a cross-section of the nozzle.

Preferably the thickness of the wall of the discharge members (6. g. nozzle 1) is about 15 millimeters in the case of iron being employed, and at least 10 millimeters in case a material of greater hardness is used. The length of the discharge member is dependent on the circumstances for which it is used; preferably it will not be less than 100 millimeters, as by a greater-length the wear, which cannot be absolutely avoided, is reduced. 1

By applying the method of extraction according to the present invention, even under difficult circumstances a relatively quiet and re ular discharge may be obtained. The qulet ejection reduces the tendency of the lining of the well to warp, and at the same time prevents the oil bed from breaking ofl.

Claim:

Apparatus for extracting liquids or gases, under pressure and containing granular material, from wells, comprising a discharge pipe connected substantially horizontally to Mill the casing of the Welland provided at its In testimony whereof I have hereunto set outer end with a, tubular nozzle of considermy hand in' presence of two subscribing wit- 10 able length, the bore of which has 'a-dinesses.

ameter smaller than that of the bore of the J E N EH) g pipe,'the nozzle bore being coaxial with the bore of the pipe and being rounded at. its Witnesses; inner end to reduce the wear caused by the THOM A. V Y granular material. KUUN WYNBBANT.
